FreeRTOS

Hi Bill,

I’m a retired computer programmer and have been a subscriber to the DroneBot Workshop for several years. I have a suggestion for a topic that I don’t remember having seen you cover. It’s the FreeRTOS that is built into the ESP32 and also the stand-alone version that can be used on other microcontrollers.

It’s especially useful on the dual core ESP32’s where you could possibility have one core dedicated to a time critical task, and the other core dedicated to non-time critical functions such as a user interface.

A few specifics that come to mind are:

• Creating the tasks
• Task priority
• Inter task communication, especially between cores (mutexes, semaphores, and queues)
• Debugging (when/if it crashes)

I don’t claim to be an expert, but I’ve used it off and on for several of my hobby projects and found it very useful.

Thanks,

Jack
